Add `--version` option to create-belt-app command

[codeofdiego]

npx create-belt-app --version should display the currently available version of Belt that is going to be used when generating a new app. It should not display all of the Belt intro content (eg. “👖 Belt 👖”). Verifying the version of Belt will help identify issues when reporting bugs and check on available features on the version.

Acceptance Criteria

When running the command npx create-belt-app --version
I see the current Belt version output as a simple text major.minor.patch format.
